They can just do what parts of NY and NJ have done. Make it ILLEGAL to pump your own gas. That way stations are forced to hire pump boys, causing an increase in the cost of gas, which increases the taxes as some tax on a percentage and not a flat fee.
Now they not only get more tax revenue from the per-mile tax, but increased taxes on gasoline. Problem solved.
NJ has full serve only, NY does not.

I hate to burst your bubble, but NJ gas prices are cheaper than Pennsylvania or NY. And yes, we cannot pump our gas.
